Abstract
An apparatus and method for generating an internal supply voltage for a semiconductor integrated circuit, includes a first voltage generator which generates a voltage in response to a predetermined characteristic of the semiconductor integrated circuit, a second voltage generator which generates a second voltage from a reference voltage generator, and a selecting circuit which selects from among the first and second voltage. The selected voltage is suppled to an internal supply voltage generator which generates therefrom an internal supply voltage for the semiconductor integrated circuit. The first voltage is selected for regulating the internal supply voltage, being controlled in level according to the characteristic of the semiconductor integrated circuit.
